Cacti have several key adaptations that enable them to thrive in arid environments. They possess thick, waxy skin that reduces water loss and minimizes evaporation. Additionally, their spines, which are modified leaves, provide shade and deter herbivores while also reducing air flow around the cactus, helping to conserve moisture. Furthermore, many cacti utilize a specialized form of photosynthesis called CAM (Crassulacean Acid Metabolism), allowing them to open their stomata at night to take in carbon dioxide while minimizing water loss during the hot daytime hours.
